چکیده

We report the results of a search for T, CP, CPT, and violation in B0-B0 mixing using an inclusive dilepton sample collected by the BABAR experiment at the PEP-II factory. Using a sample of 232 x 10(6) BB pairs, we measure the T and CP violation parameter |q/p| - 1 = (-0.8 +/- 2.7(stat) +/- 1.9(syst) x 10(-3), and the CPT and CP parameters Imz = (13.9 +/- 7.3(stat) +/- 3.2(syst)) x 10(-3) and Delta Gamma x Rez = (7.1 +/- 3.9(stat) +/- 2.0(stat)) x 10(-3) ps(-1). The statistical correlation between the measurements of Imz and Delta Gamma x Rez is 76%.

J ul 1 99 7 Determination of the CKM unitarity triangle by B → X d l + l − decay

We attempt to extract the angle γ of the Cabibbo-Kobayashi-Maskawa matrix by the inclusive B → Xd l+ l decay in the Standard Model. An independent information for the angle is coming out from the non-trivial contribution due to CP violation factor, which induces CP asymmetry in the channel. The decay rate and asymmetries are examined with including the long-distance contributions due to vector-...

We present results on the mixing parameter ∆md and tests of the CPT symmetry in the B0 dB 0 d mixing from the time evolution of dilepton events on the Υ(4S) resonance. The analysis is based on a 5.9 fb−1 data sample collected by the Belle detector at the KEKB accelerator from January to July of 2001. We obtain ∆md = 0.463 ± 0.008 (stat) ± 0.016 (syst) ps−1. No evidence for CPT violation is foun...

CPT-violating Observables in Meson Decays

We present a general model-independent and rephase-invariant formalism that cleanly relates CP and CPT noninvariant observables to the fundamental parameters. Different types of CP and CPT violations in the K0-, B0-, B0 s and D 0-systems are explicitly defined. Their importance for interpreting experimental measurements of CP and CPT violations is emphasized. In particular, we show that the tim...

Difference in B+ and B0 direct CP asymmetry as an effect of a fourth generation.

Direct CP violation in B0 --> K+ pi- decay has emerged at the -10% level, but the asymmetry in B+ --> K+ pi0 mode is consistent with zero. This difference points towards possible new physics in the electroweak penguin operator. We point out that a sequential fourth generation, with sizable V(t' s)* V(t' b) and near maximal phase, could be a natural cause. We use the perturbative QCD factorizati...

∆t-dependent equal-sign dilepton asymmetry and CPTV effects in the symmetry of the B –B̄0 entangled state

In this paper we discuss experimental consequences of a novel kind of CPT violation which would manifest itself in the symmetry of the entangled initial state of B0 and B̄0 through their loss of indistinguishability. The “wrong” symmetry component is proportional to ω. We focus our theoretical study on the ∆t-dependence of observables concerning equal-sign dilepton events for which the intensity...

On Puzzles and Non-Puzzles in B → ππ, πK Decays

Recently, we have seen interesting progress in the exploration of CP violation in B0 d → π+π−: the measurements of mixing-induced CP violation by the BaBar and Belle collaborations are now in good agreement with each other, whereas the picture of direct CP violation is still unclear. Using the branching ratio and direct CP asymmetry of B0 d → π−K+, this situation can be clarified. We predict Ad...
